Today we published the results of this quantum supremacy experiment in the
Nature article, “Quantum Supremacy Using a Programmable Superconducting
Processor”. We developed a new 54-qubit processor, named “Sycamore”, that
is comprised of fast, high-fidelity quantum logic gates, in order to
perform the benchmark testing. Our machine performed the target computation
in 200 seconds, and from measurements in our experiment we determined that
it would take the world’s fastest supercomputer 10,000 years to produce a
similar output. | G****o

也就是google的这个只比传统计算机快了45倍，估计够不上量子计算机吧。

下比传统计算机快很多。 | Y***i

完全是为这个记录搭的
没有实际应用
但确实比传统计算机快
